Title: Improvements relating to pneumatically operated machine tools
IPC: B24B33/02
Filed: 1945-09-27
Abstract: 600,098. Pneumatically-operated honing and other machines. BULLOWS & SONS, Ltd., A., and BOYCE, G. B. Sept. 27, 1945, No. 25117. [Class 60] Means for imparting reciprocating movement to a part of a machine tool comprises the combination of at least one cylinder and plunger capable of relative sliding movement under the action of compressed air, a reversing valve operable both by hand and pneumatically for controlling the flow of air to and from the cylinder, a pair of tappet-actuated valves for controlling the flow of air to the pneumatic actuating means of the reversing valve, and a manually-controllable valve situated between the pneumatic actuating means of the reversing valve and one of the tappet-actuated valves and arranged so that closure of said manually controllable valve prevents the actuation by compressed air of the reversing valve to one of its positions. The head f carrying the rotary spindle a of a honing tool is reciprocated vertically by pistons b working in cylinders c and operated by compressed air under the control of a reversing valve A provided with handle u for hand operation and also actuated by compressed air under the control of valves 2, 2 ; these are actuated by a sleeve 9 slidable on a tappet rod 10 secured to the head f and carrying adjustable tappets 12. A valve 14 is provided between the reversing valve and that tappet valve 2 which effects reversal of the valve h at the end of the normal upstroke of the head ; the valve 14 is normally open, but when plunger 17 is pushed in to switch off, through lever 19 and rod 16, the electromotor driving the honing tool, this closes the valve 14, so that the head continues its motion until it reaches the end of its normal upstroke, and then continues to a retracted position in which it abuts a stop. Counting mechanism may be provided to operate the valve 14 after a predetermined number of reciprocations ; this comprises a spring-loaded ratchet-wheel 22 having a pin 27 initially in engagement with an adjustable stop 28 ; movement of the tappet sleeve 9 at each end of the stroke actuates a pawl 24 through a pin 29a, which serves to centre the tappet sleeve 9 ; the pin 27 eventually contacts the tail 19a of the lever 19, thus closing the valve 14 and opening the motor switch. In a modification, the downward stroke is made by compressed air, the upward stroke being effected by liquid subject to the compressed air pressure. The invention is stated to be applicable to other forms of machine tools in which it is required to impart reciprocatory motion to a tool or work-piece.

Title: Process for the production of uranium tetrafluoride from uranium raw material
IPC: C01G43/06
Filed: 1958-08-06
Abstract: Uranium tetrafluoride is produced by leaching a uranium raw material with sulphuric acid adding a solution of uranous ions to reduce ferric ions to ferrous ions, extracting with an organic solvent, stripping to form an aqueous uranium-containing sulphate solution, electrolytically reducing to the uranous state and precipitating uranium tetrafluoride by the addition of hydrogen fluoride.  A portion of the uranous sulphate solution from the electrolytic reduction is recycled to treat fresh leach liquor. Organic solvents specified are di-2-ethylhexyl phosphoric acid in kerosene, with or without tributyl phosphate.  The organic solvent may be stripped with sodium carbonate solution and the resulting uranyl carbonate solution is then treated with sulphuric acid, or the stripping may be effected with 10N sulphuric acid.

Title: Apparatus for supplying lubricant to tools or devices driven by compressed air
IPC: F16N7/34
Filed: 1971-04-19
Abstract: 1343988 Lubricator MASTER PNEUMATIC-DETROIT Inc 19 April 1971 [25 March 1970] 25207/71 Heading F2A A lubricator for a pneumatically operated tool comprises a lubricant pump which is actuated by the start of the air flow to the tool, the lubricator supplying a constant dose of lubricant on each actuation. Air supplied to the tool is fed via a duct 32 to the lubricator. The air flow depresses a disc 46 against a spring 56 which lowers a piston 48 thereby opening a port 108 which allows air to be fed through a duct 110 to the lubricant pump 68. The pump has a piston 88 which is reciprocated across a lubricant supply pipe. The piston 88 is actuated by air pressure acting on a disc 86 which is biased by a spring 91. The piston 88 forces lubricant past the non-return valve 96 through alubricant duct to the tool. The amount of lubricant delivered at each stroke is adjusted by the screw 168. On cessation of the air flow, the piston 48 rises under the action of spring 56, and a sealing ring 122 covers the ports 108. The tube 50 then rises with the piston thereby opening a vent valve 134 to allow air to escape from the pump to reset the pump for the next cycle.

Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T15/04
Filed: 1934-09-04
Abstract: 443,966. Fluid - pressure brakes. SIMMONS, A. W., and WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London. Sept. 4, 1934, No. 25473. [Class 103 (i)] In a driver's valve an additional or fast service position is interposed between the service and emergency positions in which a circuit of an electromagnetic valve is opened by the movement of the driver's valve, to release fluid from the train pipe, this circuit is also open in emergency position but closed in release, running, lap and service positions. The electromagnetic valve 11 is adapted when de-energized to be seated on its lower seat by a spring 12 and connect a chamber 16 to a passage 14. The chamber 16 is connected by a check valve with a chamber 21 connected to the train pipe and the passage 14 is connected to a venting chamber 15. When the valve 11 is energized and raised it closes connection between the train pipe and the chamber 15 and connects the bulb 15 to atmosphere by passages 31, 32, chamber 28 and passage 29. In the event of the valve 11 becoming improperly de-energized, i.e. when the driver's valve is not in fast service or emergency positions and during an ordinary service brake application, a relay valve 26 is opened, when the train pipe pressure is reduced by the driver's valve, pneumatically, to connect the train pipe to atmosphere by chambers 21, 27, 28 and passage 29 to effect a full brake application. The pressure in the chamber 21 falls with train pipe pressure and causes the piston 19 to open the valve 26 only when the capacity of the chamber 16 has been increased by connection to the chamber 15 by the valve 11, the capacity of the chamber 16 alone being insufficient to effect movement of the piston 19. When the valve 11 is improperly de-energized in running or release, a brake application is produced by connection of the train pipe to the bulb 15. The bulb 15 may have a restricted atmospheric port, or the bulb may be dispensed with and the valve 11 may connect the train pipe to atmosphere.
